How Long Does Car Battery Last Without Engine. I dont get it. Depending on how old the car battery is it takes about 2 and a half months on average to drain out a whole car battery.
Earlier say about 8 to 10 years ago typical car batteries were made in a manner that you could open the small cap near the terminal put some distilled water in it and get y. Also if I start the car and just let it idle for 5-10 minutes will that recharge the battery or do I need to actually drive the car and get my speeds above 60mph. If your alternator crapped out it might be cheaper to buy a battery and charge the one in the car to get home depending on the distance and then install the spare alternator once you got the car home.
Depending on the vehicle you can let your car sit for months at a time if you plan to have a storage methodology in place.

BMW says Four weeks is the max for storage without removing the battery or putting it on some form of life support or a battery. The battery keeps your vehicles energy system sustainable. In todays times car batteries have a typical life of 4 years give or take a couple of weeksmonths.
